National Non-Point Source Pollution Program	NNPSPP		Abbreviation and Acronym List			
Non-Point Source Pollution		Aquatic Biodiversity Glossary 	Glossary and Key Word List		Definition: Pollution that occurs when rainfall, snowmelt, or irrigation runs over land or through the ground, picks up pollutants, and deposits them into rivers, lakes, and coastal waters or introduces them into ground water.
	
Non-Point Source Pollution		Biocriteria Glossary 	Glossary and Key Word List		Definition: Pollution that occurs when rainfall, snowmelt, or irrigation runs over land or through the ground, picks up pollutants, and deposits them into rivers, lakes, and coastal waters or introduces them into ground water.
	
Nonpoint Source Pollution		DWMAPS Glossary 	Glossary and Key Word List		Definition: Pollution that is not released through pipes but rather originates from multiple sources over a relatively large area. Nonpoint sources can be divided into source activities related either to land or water use including failing septic tanks, improper animal-keeping practices, forestry practices, and urban and rural runoff.
	
Nonpoint source pollution		Total Maximum Daily Loads (303d) Glossary 	Glossary and Key Word List		Definition: Pollution that is not released through pipes but rather originates from multiple sources over a relatively large area. Nonpoint sources can be divided into source activities related either to land or water use including failing septic tanks, improper animal-keeping practices, forestry practices, and urban and rural runoff.
	
Nonpoint Source Pollution		AgSTAR Handbook Glossary 	Glossary and Key Word List		Definition: Pollution resulting from intermittent discharges of pollutants from diffuse sources and is in transit over land before entering a water body.
	
Nonpoint Source Pollution		Web Taxonomy-Environmental Media Topics 	Taxonomy		Definition: Nonpoint Source: Any source of pollution not associated with a distinct discharge point. Includes sources such as rainwater, runoff from agricultural lands, industrial sites, parking lots, and timber operations, as well as escaping gases from pipes and fittings. (Environmental Issues Glossary) Nonpoint Source Pollution: Pollution sources which exhibit any of the following characteristics: are diffuse, do not have a single point of origin, or are generally carried off the land by stormwater runoff. (TX NRCC Local Gov Guide) Nonpoint Source Pollution: Pollution sources that are diffuse, without a single identifiable point of origin, including runoff from agriculture, forestry, and construction sites. (Contaminated Sediment Glossary) Nonpoint Sources: 1: Diffuse pollution sources (i.e., without a single point of origin or not introduced into a receiving stream from a specific outlet). The pollutants are generally carried off the land by storm water. Common non-point sources are agriculture, forestry, urban, mining, construction, dams, channels, land disposal, saltwater intrusion, and city streets. (TofE)
	
Nonpoint Source Pollution		Contaminated Sediments Glossary &Acronyms 	Glossary and Key Word List		Definition: Pollution sources that are diffuse, without a single identifiable point of origin, including runoff from agriculture, forestry, and construction sites.
	
Nonpoint Source Pollution		Impaired Waters and Total Maximum Daily Loads Glossary 	Glossary and Key Word List		Definition: Pollution that is not released through pipes but rather originates from multiple sources over a relatively large area. Nonpoint sources can be divided into source activities related either to land or water use including failing septic tanks, improper animal-keeping practices, forestry practices, and urban and rural runoff.
	
Nonpoint Source Pollution		Economic Benefits of Runoff Controls Glossary 	Glossary and Key Word List		Definition: Water pollution caused by rainfall or snowmelt moving over and through the ground which carries pollutants. A nonpoint source is any source of water pollution that does not meet the legal definition of point source in section 502(14) of the Clean Water Act.
	
Nonpoint Source Pollution		How's My Waterway Glossary 	Glossary and Key Word List		Definition: Nonpoint Source pollution is a pollution source without a single point of origin or specific outlet. NPS pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. NPS pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.
	
Nonpoint Source Pollution	NSP		Abbreviation and Acronym List			
Point Source Pollution		AgSTAR Handbook Glossary 	Glossary and Key Word List		Definition: Pollution entering a water body from a discrete conveyance such as a pipe or ditch.
	
Point Source Pollution		Impaired Waters and Total Maximum Daily Loads Glossary 	Glossary and Key Word List		Definition: Pollutant loads discharged at a specific location from pipes, outfalls, and conveyance channels from either municipal wastewater treatment plants or industrial waste treatment facilities. Point sources can also include pollutant loads contributed by tributaries to the main receiving water stream or river.
	
Point Source Pollution		Contaminated Sediments Glossary &Acronyms 	Glossary and Key Word List		Definition: Point source pollution refers to the pollution that comes from a specific, identifiable source, such as a pipe or channel.
	
Point source pollution		Total Maximum Daily Loads (303d) Glossary 	Glossary and Key Word List		Definition: Pollutant loads discharged at a specific location from pipes, outfalls, and conveyance channels from either municipal wastewater treatment plants or industrial waste treatment facilities. Point sources can also include pollutant loads contributed by tributaries to the main receiving water stream or river.
	
Point Source Pollution (or Point Source Discharge)		DWMAPS Glossary 	Glossary and Key Word List		Definition: Pollutant loads discharged at a specific location from pipes, outfalls, and conveyance channels from either municipal wastewater treatment plants or industrial waste treatment facilities. Point sources can also include pollutant loads contributed by tributaries to the main receiving water stream or river.
